If your dog door flaps are looking worn out or damaged, these Yicostar replacement flaps will have your pet door working like new again! This two-pack gives you backup flaps so you're always prepared. The extra large size measures 23.6 inches high by 13.8 inches wide, making them perfect for bigger dogs up to 220 pounds - no more squeezing through tight openings for your large breed pets. Made from durable, non-toxic material that's weather resistant, so they can handle sun, rain, and temperature changes without cracking or becoming brittle. The installation is super straightforward - just remove your old worn-out flaps and slide these new ones into place. Having two flaps provides that nice double barrier that helps with insulation and keeping out drafts, bugs, and debris. The material has just the right amount of flexibility - stiff enough to seal properly but soft enough for your dog to push through comfortably. Perfect for replacing flaps on Yicostar brand dog doors, but they might work with other similar sized pet doors too. The clear material lets your pet see through to the other side, which helps them feel more confident using the door. Much more affordable than replacing the entire dog door system, and the quality feels substantial and well-made. Whether your current flaps are torn, stiff with age, or just not sealing properly anymore, these replacement flaps will restore your pet door to full functionality and keep your home better insulated from the elements.
